High Availability

High Availability

In this section, we will explore two distinct High Availability scenarios: single-box Deployment with High Availability and Distributed Deployment with High Availability. Each scenario presents unique configurations, prerequisites, and architecture designed to ensure a robust and fault-tolerant architecture.

Whether you opt for a consolidated single-box Deployment or a distributed setup, Motadata AIOps' High Availability deployment empowers your organization to navigate potential disruptions with confidence. Dive into the detailed explanations and accompanying diagrams to gain valuable insights into implementing High Availability, safeguarding your IT infrastructure, and fortifying your operational capabilities.

Single-Box Deployment with High Availability

Architecture

In a single-box Deployment with High Availability, Motadata AIOps employs a primary-secondary server configuration to ensure continuous availability. A virtual IP is configured to ensure uninterrupted service of Motadata AIOps to the user. This server setup forms the foundation for the High Availability architecture, allowing for a failover mechanism to take over in case of any failure.

In HA setups employing a single-box configuration, the Observer is intricately connected to both the primary and secondary components. This connection enables real-time synchronization of critical data.

• Continuous Heartbeat Exchange: The Primary and Secondary servers maintain constant communication by sending heartbeats to each other. This continuous heartbeat exchange ensures real-time monitoring of server availability status.

• Virtual IP Configuration: A Virtual IP is configured to ensure uninterrupted connectivity to Motadata AIOps for the end user.

• Agent and Collector Registration: Ensure the registration of all collectors and agents is done through the Virtual IP address. This will ensure the requests are being sent to the active application server in the event of a failover.

• Failover Trigger: The failover mechanism is designed to activate when the Primary server fails to send a heartbeat to the Secondary server within a pre-defined interval. This failover process ensures activation of the Secondary server as the Primary server, mitigating potential downtime.

• Activation of Slave Server: Upon detection of a failure, the Secondary server automatically takes over as the Primary server. This swift transition due to the configured virtual IP ensures continuous service availability.

• Role of Observer: The Observer retrieves data every 10 seconds from the Primary component, including configuration database and cache. This data is then stored within the Observer itself and synchronized with the Secondary component. This synchronization mechanism ensures that the configuration database and cache remain consistently updated across all components within the HA setup.

• Database Synchronization: Report DB of both Primary and Secondary components remains in sync through registration of slave component with the master component, ensuring data consistency and accessibility across the architecture.

• Restoration Process: Once the original Primary server is restored and operational, it resumes its role as the Primary server. The restoration is initiated after the Primary server sends a heartbeat to the Secondary server, confirming its availability.

This orchestrated process ensures a resilient High Availability single-box Deployment for Motadata AIOps, where servers communicate with each other, failover occurs promptly, and service continuity is prioritized.

Configuration

1. Configure three Physical IPs (one for Primary server, one for Secondary server, and one for observer) and a Virtual IP (for seamless user access and failover scenario) as per the single-box deployment scenario.

2. Configure the Observer server as per Single-Box High Availability scenario from the Installation Guide

3. Configure Primary Server as per the Single-Box High Availability scenario from the Installation Guide

4. Configure Secondary Server as per the Single-Box High Availability scenario from the Installation Guide

Distributed Deployment with High Availability

Architecture

In a Distributed Deployment with High Availability, the Primary server is connected to two separate sets of MotaStores, Primary DB and Secondary DB at the main site, ensuring redundancy and real-time data updates in case of failure. A virtual IP is configured to ensure uninterrupted access to the end user.

In distributed HA deployments, the Observer maintains connections with the Primary and Secondary application servers. This ensures comprehensive real-time synchronization of critical data.

• Continuous Heartbeat Exchange: The Primary and Secondary application servers engage in continuous communication through heartbeat exchanges. This ongoing communication allows real-time monitoring of server availability status.

• Virtual IP Configuration: A Virtual IP is configured to ensure uninterrupted connectivity to Motadata AIOps for the end user.

• Agent and Collector Registration: Ensure the registration of all collectors and agents is done through the Virtual IP address. This will ensure the requests are being sent to the active application server in the event of a failover.

• Config DB Synchronisation: The Observer retrieves data every 10 seconds from the primary Application Server, including configuration database and cache. This data is then stored within the Observer itself and synchronized with the Seccondary application server. This synchronization mechanism ensures that the configuration database and cache remain consistently updated across all components within the HA setup.

• Report DB Configuration: Deploy two sets of MotaStores to support redundancy and fault tolerance. The Primary application server maintains connections to both sets of MotaStores. Report DB of both Primary and Secondary Motastores remains in sync through registration with the Primary application server, ensuring data consistency and accessibility across distributed environments.

• Failover Mechanism: The failover mechanism triggers when the Primary application server fails to send a heartbeat to the Secondary application server within a predefined interval. This failover process ensures activation of the Secondary application server as the Primary server, mitigating potential downtime. In case, the Primary DB goes down, the Secondary DB seamlessly connects to the Primary Application server again mitigating potential downtime in this case.

• Activation of Slave Server: Upon detection of a failure in the Primary Application server, the Secondary Application server automatically takes over as the Primary server. This transition minimizes service disruption and maintains continuous availability due to the configuration of the virtual IP.

• Restoration Process: Once the original Primary Application server is restored, it resumes its role as the Primary Application server after sending a heartbeat to the Secondary Application server. The restoration process completes the cycle, ensuring a seamless transition back to the original configuration.

This orchestrated architecture ensures a resilient Distributed Deployment with High Availability for Motadata AIOps. The continuous communication, redundancy, and failover mechanisms collectively contribute to maintaining operational excellence.
